I have weighing machine which have serial RS-232C interface card for connecting the AD-4321 to printers, PC.

Specifications:
Type EIA ¡V RS-232C ¡V Passive 20mA current loop
Method half ¡V duplex, asynchronous transmission
Format Baud rate : 600 or 2400 (dip ¡V switch selectable)
Data bits : 7
Parity bit : 1 (even)
Code : ASCII


Data format
ST GS +1234 56KGcrlf

ST ¡V HEADER 1
GS ¡V HEADER 2
+1234.56 ¡V DATA
KG - UNIT
crlf - Terminator


How to read into the Serial RS-232C and get the data and save into the text file or dbf file. How to implement by using VFP. Coding will be appreciated. Thanks
